Power Steering unit replacement
You need to buy the tool to remove the power steering pump pulley, the power steering pump comes without a pulley.
The special tool screws into the shaft thread, then place the tool around the pulley hub and cover with the ring. then turn the big nut and the pulley will come off.
(they will have instructions with the kit)
You will need to use the tool to fit the pulley on the new pump, DO NOT TRY STANDARD PULLERS you will buckle the pulley.
You may be able to hire the tool, a lot of guys on this forum will have one of these in their garage.
But i am a bit far away here in Australia
